Connector for a wooden backrest of a chair

ABSTRACT

A connector for a wooden backrest of a chair, wherein the connector is configured as a tube with a top opening and a bottom opening. The wooden backrest is constituted of an upper part and a lower part and each part having ends to be force fitted into the top opening and the bottom opening of the connector respectively, and thereby connects the upper part and the lower part together to form the backrest in order to efficiently consume wood in manufacture of the chair and assist in environmental protection concern.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a connector, and moreparticularly to a connector for a wooden backrest of a chair such thatthe connector is used to connect an upper part and a lower part of thebackrest together for the purpose of reducing both the cost of the chairand environmental protection concern.

[0003] 2. Description of Related Art

[0004] Chairs are a kind of common house furniture that people have usedfor centuries, and there are various types of chairs available in themarket. With reference to FIG. 5, a conventional chair commonly seen isshown. The chair has a support (50), a backrest (52) securely connectedto the support (50), and a seat (54) mounted on the support (50). Thebackrest (52) further has two rods (522) formed parallel to each otherand at least one cross rail (524) connecting the two rods (522).Although there are a lot of materials that can be used to produce thechair mentioned, wood is the preferred kind among the materials to makethe main structure of the chair, that is, the support (50) and thebackrest (52). However, the cost of wood depends on its length, and fromobserving the figure it is obvious that the longest component of thechair is the rod (522) of the backrest (52). Therefore, if the rod (522)can be formed by assembling two separate rods instead of an integralrod, the cost of the chair can be reduced. Moreover, wastefulmanufacture of chairs in the manner described is one more burden onforest management and epitomizes the destruction of our precious naturalresources. Therefore, assembling two short rods into a long rod to formthe rod (522) of the backrest (52) is a “green concept” in relation toenvironmental protection concern.

[0005] Accordingly, the present invention tends to provide a connectorfor a wooden backrest of a chair to mitigate or obviate theaforementioned problems.

SUMMARY OF THE INVENTION

[0006] An objective of the present invention is to provide a connectorfor a wooden backrest of a chair such that the connector is able toconnect multiple short rods into a long rod to form a rod of thebackrest of the chair so as to reduce both the cost of the chair andenvironmental protection concern.

[0007] Other objectives, advantages and novel features of the inventionwill become more apparent from the following detailed description whentaken in conjunction with the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] With reference to FIGS. 1 and 2, a chair having a connector inaccordance with the present invention is shown. The chair has a support(10), a seat (20), and a wooden backrest (40) having two connectors(30).

[0014] The support (10) rests on the ground and bears a seat (20)mounted thereon. The support (10) and the seat (20) are well knownarticles thus detailed description is omitted. The backrest (40) has anupper part (402) and a lower part (404). The upper part (402) isconstituted of two upper rods (4022) formed parallel to each other andat least one cross rail (4024) connecting the upper rods (4022) to eachother. Tile lower part (404) has two lower rods (4042) formed parallelto each other and securely connected with the support (10). The lowerrods (4042) are spaced apart from each other in a distance correspondingto a distance between the upper rods (4022).

[0015] With reference to FIGS. 3 and 4, each connector (30) has aconfiguration of a tube with a top opening (302) and a bottom opening(304) to respectively connect the upper part (402) and the lower part(404) together. When assembling the backrest (40), two bottom ends ofthe upper rods (4022) are respectively force fitted into the topopenings (302) of the connectors (30). Then the connectors (30) areconnected to the lower part (404) of the backrest (40) by respectivelyforce fitting top ends of the lower rods (4042) into the bottom openings(304) of the connectors (30). Therefore, the connectors (30) connect theupper part (402) and the lower part (404) to form the backrest (40).

[0016] It is noted from the above description that the connector (30)has the advantage and function of connecting the upper rods (4022) withthe lower rods (4042) instead of using integral rods as of theconventional chair, in order to reduce the cost of the chair and also toprotects the environment.

[0017] While this invention has been particularly shown and describedwith references to the preferred embodiment thereof, it will beunderstood by those skilled in the art that various changes in form anddetails may be made therein without departing from the scope of theinvention encompassed by the appended claims.

What is claimed is:
 1. A connector for a wooden backrest of a chair, thewooden backrest having an upper part and a lower part, the upper parthaving at least one upper rod and the lower part having at least onelower rod, the connector comprising: a tube having a top openingconfigured for force fitting with a bottom end of the at least one upperrod, and a bottom opening configured for force fitting with the top endof the at least one lower rod, whereby the connector connects the upperpart and the lower part of the wooden backrest together.
